CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 364,583, dated June 7, 1887.

` Application filed March 2S, 1887. Serial No. 239.503. (No model.)

Be it known that I, MARTIN A. EIsENHoUR, acitizen of the United States, residing at Plymouth, in the county of Marshall vand State of Indiana, have invented certain new and usclful Improvements in Gultivators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and Iigures of reference marked thereon.

Figure l of the drawings is a perspective view of a cultivator embodying Inyinvention; Fig. 2, a detail view in perspective of the clip for holding the oultivator tooth; Fig. 3, a similar view in section of the clip, the cultivator-tooth, and the tooth-bar, the bolts which connect the two sections of the clip together being shown in dotted lines; and Fig. 4 is a detail view showing the manner of connecting the braces to the tooth-bar.

The object of the present invention is to provide simple and practical means for attaching the tooth-bar to the beam of the cultivatorframe, and also in connecting the teeth to the bar, as will be hereinafter described and claimed. l

In the accompanying drawings, Arepresents the usual cultivator-frame, to which is connected the tooth-bar B, which may be of any desirable length for carrying the required number of teeth. The bar B is so constructed as to be attachable to any form of common cultivator bymeans of the slots c in the bar, through which pass clamping-hooks C, screw-threaded at their shank end, as shown at b, to receive nuts c, a washer being interposed between the nut and bar, as shown at d, Fig. 4. The hooked end of the clamping-hook C extends around the lower end of the posts D, there being twoposts connected to the bar, as above described, the upper ends of said posts being suitably connected to the beam of the cultivater-frame. Should the distance between the lower ends of the posts D vary', the clamping-hook C Inay be moved along the slot a in a direction to or from the ends of the bar B, to adapt them to the position of the post, so that the hooked ends will extend around the same.

s If the slots c are not sufficiently long to at 'tain the purpose above described, theyhooks may be moved to the extremities of the slot, as shown in Fig. 4, and afterward turned so L that their hooked ends will be opposite to the position shown, thereby reaching the distance from one post to the other.

In order to bring the teeth on different verltical planes, the angle of the bar B can be changed by removing one of the clamps C and replacing it ina reversed position, so that one of the posts will be connected to the front side of the beam and the other post on the rear side thereof, thereby bringing the bar from a right angle to an acute angle'with the line of draft.

lf it is desired to use the bar for other than spring teeth, the bolts that hold the clips, hereinafter described, may be removed and the shank of the bolt or hook inserted through the bolt-holes. y

The cli p, which is intended to hold the tooth firmly in its place to the bar B, (any forni of springtooth,) consists of the two sections E F, the upper section, E, being in the form of a cap-plate, withholes e for the fastening-bolts to pass through, as shown in dotted lines, Fig. 3. The lower section,F,is preferablyserrated upon its under side, to prevent it from slipping on the bar B, to which it is attached by the single bolt f and nut g, the'latter passing through the bar, as shown in Fig. 3; and when the two sections of the clamp are together the tooth G 4 is firmly held between them.

The center of the clip-section F is countersunk, as shown at h, for the reception of the head of the bolt f, as is also the ends of said section, as shown at t', for the reception of the heads of the bolts that connect the two clipsections together.

The section F is sunken upon its upper side to receive the tooth and form a seat therefor, the outer edges of which are slightly convex, as shown at lc. At each end of this sunken. space are shoulders Z, which are concave, as shown, and the cap-plate E is concave-convex,

in cultivators; and when spiketeeth are used the bolts f nrc removed and the Shanks of the A teeth inserted in their place, ns hereinbcfore described. Y

Having now fully described my invention, what I clztini ns new, and desire to secure by Letters Patent, is-
